The world's only highway-capable electric performance vehicle is now available in the land down-under.

While Americans are left wondering who killed the electric car, clean car enthusiasts in Australia are lining up to buy the sleek new Tesla roadster; the only vehicle on the market that delivers supercar performance with zero tailpipe emissions.

With a handmade, carbon fiber frame, the Roadster can accelerate from 0-100km in less than four seconds and consumes no petroleum. Able to be plugged into any conventional socket, the Roadster can travel over 380 kms on a single charge.

No charging station available? No problem. It's also the only sports car in the world that can be powered with solar, hydro or wind energy. This is especially useful in Australia, a country that experiences an average of 2,633 hours of sunlight per year with an average of 7.2 hours of sunlight per day.

The Tesla Roadster was only recently approved for Australian roadways and is now available for purchase. In the United States, however, clean cars have been much slower in reaching consumers. Although electric and hydro car technologies exists, American auto makers are still reluctant to bring them to market.

The new National Fuel Efficiency Policy recently enacted by the Obama administration marks the first time in U.S. history that the federal government has regulated global warming pollution under the Clean Air Act. Unfortunately, some feel the goals of the new policy are too conservative, demanding only an average fuel economy standard of 35.5 mpg by 2016.
